Is IgG useful for Wechseljahre?

The question of whether IgG testing is useful for menopause cannot be answered with robust evidence from the provided knowledge base. IgG antibodies are often measured in commercial food sensitivity panels, but the scientific validity of such tests is controversial. For menopausal symptoms like hot flashes, sleep disturbances, or mood swings, there is no established role for IgG. Menopause is primarily hormonal; IgG tests do not provide direct information about hormone status or metabolism. If a food intolerance is suspected, controlled elimination diets under medical supervision are more reliable. The evidence level is 'marketing' or 'unclear', as the study base for IgG in this context is weak. Caveat: IgG tests can lead to unnecessary dietary restrictions and anxiety. For menopause, established biomarkers like FSH, estradiol, and TSH, along with a clinical consultation, are more appropriate.
